SPECIFICATION forming part of Letters Patent No. 3737,226l dated March 2,1886.

Application filed J une 10` 1885.

To all whom, t may concern.-

Be it known that I, GARDNER C. ANTHONY, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Gas-Engines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to that class of gas-engines in which the combustion of the gas takes place in a cylinder or generator, and in which the pressure generated is utilized in a separate working cylinder.

The invention consists, first, in the construction and arrangement of the generator, the cylinder, and the piston, and the arrangement of the air and gas ducts, the restorer, and refrigerator, in combination with the working cylinder and piston, by means of which a combustible mixture may be exploded in a cylinder the piston of which is subjected to equal pressure on both sides during and after the combustion of gases, the pressure being utilized in a second cylinder.

Ihe invention consists, secondly, in producing compression in the generator-cylinder previous to the combustion of gases by passing the air from one sideof the piston to the other through the restorer, thus heating the same and augmenting the same by a reduction in volu me due to the travel of the piston in the Working cylinder.

My invention consists, thirdly, in the transfer of pressure by the combustion of gas to the working cylinder by means of an intermediate volume of air.

The invention consists, finally, in certain peculiar and novel features of general construction of parts and arrangement of connections, all as hereinafter described and claimed.

In order that my invention may be-fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure l is a View, partially -in elevation and partially in section, of my improved engine. Fig. 2 is a similar view of the same on a plane at right angles to that of Fig. l. Fig. 3 is a plan view of Fig. 2.

In the said drawings, A designates the working cylinder, containing a piston, B.

Serial No. 168,220. (No model.)

lining, C', of refractory material, by means of which the cylinder and its piston are protected SaidJ from the extreme heat of combustion. generator is also provided with a valve, E, working over an inlet-port, e, through which and a channel, e', the air enters beneath piston D. At its upper end the generator `is provided with a valve, G, for the admission of gas, andworking over an inlet, g, through Y which the combustible gas enters above piston D.

The refrigerator K consists of a chamber containing a series of tubes, k, through which water is forced, and communicating with the lower end of generator O by the channel e and a vertical channel, e2, as shown. The restorer F communicates with the refrigerator K through a port, e3, and with the upper end of generator O lby a channel, K. Within the restorer are placed a series of plates, f, of heatabsorbent material. The` working cylinder A communicates with the refrigerator K through a pipe, O, which enters the working cylinder above its piston B.

P designates the main shaft, which carries a crank, p, and a crank, p. A connectingrod, B', extends from crank p to piston B, and a connecting-rod, D', extends from crank pto the displacer-piston D, there being the usual cross-head, D2, for guiding the piston D.

R designates a rocking lever which is fulcrumed upon one of the supports L, and one end of which is connected to cross-head D2 by a pin, 1^, working in a slot, r', in the lever. The stem E of valve E is connected by a rod, s, with the outer-end of lever B, and the stem G of valve G is connected by a rod, s', with said lever, the arrangement of said rods being such as to impart the required vibrator-y IOO A suitable pump is used for circulatingwater through the tubes of condenser K, and a second pump is also used for supplying the combustible gas to the generator.

From the above description it will be seen that, the piston B of the working cylinder Av being at the lower end of its stroke, Fig. 2, the port e is open and connection with the lower vend of cylinder closed, and the burned gases are discharged Afrom above piston D through restorer F, causing an immediate reduction of pressure in both cylinders. At the same time fresh air is entering beneath piston D, through Valves H, into the' lower or cold end of the generator, and this continues until piston D has reached the upper end of its stroke. At this moment port e is suddenly closed,and the ends of the generator are placed in communication with each other through the condenser andY restorer. The upward movement of piston B now sets up compression, which is augmented by the expansion of v gases transferred from the restorer and refrigerator to the upper or hot end of the generator-cylinder. When such portion of the stroke of piston D has been made as is suicient to transfer that portion of the burned gas as remained inthe restorer, refrigerator, and clearance-space at the termination of the last upstroke of piston D, the gas-valve G opens and the combustible gas enters the generator, mixing with the heated air above piston D. This supply of gas is automatically controlled by a regulator, T, upon a shaft, t, carrying a beveled gear, t', meshing with a similar gear, t, on shaft P. When piston B has reached the upper end of its stroke and begins to descend, the piston D having nearly completed its stroke, the charge of heated air and gas in the hot end of the generator is. ignited by electricity or contact with flame, and the maximum of temperature and pressure is obtained, thus forcing piston B downward. The subsequent operations are a repetition of those above described. Thus it will be seen that the combustible gas is brought into vcontact with air highly heated by being passed from the cold end of the generator through a restorer, and the mixture is then exploded in the hot end of the cylinder to produce the required power; also, that the fresh air remaining in' therestorer, condenser, and clearance-space not vitiated by mixture with burned products is to be returned to the cold end of the gen erator. The burned gasesrcmaining in the restorer, refrigerator, and clearance space after the exhaust-valve closes are passed into the hot end of the generator previous to the4 admission of combustible gas.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. An improved gas-engine constructed and arranged substantially as described, whereby the piston of the generator-cylinder is subjected to equal pressure on both sides during and after combustion of gases` the pressure being utilized in a second cylinder, as described.

2. An improved gas-engine constructed and arranged substantially as described, whereby the air is passed from one side of the generator-piston to the other through a restorer to produce compression in the generator previous to combustion of gases, and heating the air and augmenting the pressure, as specified.

3. An improved gas-engine constructed and arranged substantially as described, whereby the pressure generated by the combustion of the gas is transferred to the working cylinder by means of an intermediate volume of air, as described. A

In witness whereof I have hereunto set my hand.
